Thinking in HDF5

nitinchandra1 · June 30, 2015, 2:59pm

Hello All,

I have been on this for a long time and have done a lot of research /
reading on this topic, HDF5.

To use it for development of in-house software for design calculation
of various alignments.

A lot many time the basic alignment information is picked from a map /
satellite imageries. Kilometre, ground level, geographic feature on
the proposed route, etc. , in a csv file.

Any where between 7-9 files are generated for each alignment.

1. How to read / write data into the HDF5 file ? What after creating root ?

2. In a regular situation, I have 2 input file with 3 column csv data,
and 2 output files.
How to do that within the same root ? With variable string length ?

Will be working in Python and c / c++.

This is just the basic. If I can do this much, I can do the rest, hopefully

Thanks to All

Nitin

Apologies but it is difficult to understand what your (specific) questions are.

At first, I thought your questions (which mentions map, satellite images, etc.) are related to http://hdfeos.org. I am no expert but I think HDF5-EOS is a whole community of users that develop EOS-specific software based upon HDF5. And, there appears to be a wealth of help and examples available there to start from.

OTOH, some of your questions seemed much more basic (e.g. how to write CSV data to HDF5). There are a number of examples, http://www.hdfgroup.org/HDF5/examples/, and a tutorial, http://www.hdfgroup.org/HDF5/Tutor/, that I am almost certain will contain the answers those questions.

Hope that helps.

Mark
